quent painting of the radiators to freshen their appearance is not only expensive in requiring the expenditure of considerable time and money but diminishes their effi- 'ciency as heat radiators, and as a result add to the outlay for fuel. My invention consists in the provision of a cabinet which is adapted for positioning over the radiator to hide the same from view. I am aware that it is not new to prov de a cabinet cover for radiators. but such covers as heretofore construt-tad have lessened .the elliciency of the radiators by retarding the flow of heated air therefrom and one of the principal obof my invention is to provide a cabinet cover which is constructed to "permit the heated air to flow freely therefrom so that the efiiciency' of the heating plant is not lowered thereby.-

Another ob ect is the provision of a cabinet cover for radiators which is so constructed as to be adapted for a useful and ornamental article of furniture. 4

A further object is the provision of a cabinot cover for radiators which is of hi lily economical construction by reason 0 .its walls and cover being adapted for construction from sheet metal by stamping and for its being shipped knocked down from the factory and its easy assembly by the purchaser. I

A still further object of the invention is the provision of a combined cabinet cover and humidifier for radiators constructed so that the air currents which the heated radiator put in motion are. directed over the surface of the water contained in the humidifier in surlra way that maximum saturation is obtained.

The soiling of walls and draperies by the solid particles carried from the radiators by the induced air currents is a common and heretofore unavoidable experience wlnch it is another ob ect of the lnvention to prevent by directing the air currents over the water in the humidifier in close contact with the surface and through the heated vapors arising therefrom so that the air is washed clean of said solid particles and the soiling of the walls and draperies is minimized.

The foregoing and other objects will appear in the following detailed description.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which-- Fig. 1 is a perspective view of the cabinet and humidifier as it appears when completed and in position ready for use.

Fig. 2 is a sectional view along the line 2-2 of Fig. 1.

Fig. 6 is an end view of the humidifier.

Fig. 7 is a plan view of the humidifier as it appears. when detached from the cabinet.

g. 5 is a longitudinal sectional view of Fig. 8 is a view showing a detail of an permit the free ingress of air from the room and is provided with a suitable outlet for the air at the to which has become heated by contact with t 1e radiator. The invention further consists in the provision of a humidifier pan 12 and means for directing the heated air over the surface of the water in the a pan 12 in such a way that maximum saturation occurs and the air is freed of its dust particles by its contact with the water and the vapors rising therefrom before it again escapes into the room.

In its preferred form the cabinet cover or housing 11 is rectangular in shape and is provided with vertical legs 13 at each of its corners to which the walls of the housing are fastened as by screws or bolts If The vertical walls of the housing preferably stop short of the floor and are provided with a plurality of perforations 15 through which the relatively cool air of the room enters the housing as well as through the space between the walls and the floor. Access to the housingis obtained by pivotally connecting the top wall 16 to the rear wall .17 as by hinges 18 as best indicated in Figs. 2, 3, and at. The housing llis made sulliciently. long so that the end walls 19 are spaced away from the radiator sufficiently to clear the valves and provide ample room for the insertion of the arm and hand to conveniently operate the valves-with which radiators are usually equipped.

The walls of the housing may be constructed of any desired material but are especially adapted for manufacture from sheet metal by stamping, the perforations and bends being such that they are economically formed by a minimum number of operations. Rigidityis given to the exposed end walls 19 and the front wall 20 by providing the end walls with upper and lower marginal members 21 and 22 respectively and the front wall with corresponding marginal members 23 and 24. These marginal members are preferably folded inwardly and upwardly or downwardly so that the folded portions are substantially parallel with the main outer portion of the members. The marginal members thereby resent a smooth and regular exterior whici in connection with the main wall members-l9 and 20 give a panel effect to the housing. This panel effect is enhanced by painting the housing to match the decorations of the room so that the-housing becomes an ornament to the The folds 25 and 26 on the upper marginal members and the fold 27'on the lower marginal members are spaced away from the main portion of the members of which they form a part, thereby increasing the resistance of the members to bending. The folds 26 and 27 are adapted to receive the marginal edges of the members 19 and 20, the latter being bentfor wedging engagement therewith. This featureis conducive to the housing being slnpped knocked-down? and its easy assembly. The folds E28 and 29 on the rear wall 17 add to its rigidity. The folds 25 and 9.8 also provide a support for the humidifier pan 12 in the manner hereinafter described.

The top wall 16 has its marginal edges turned down to form a flange 30 which adds to the appearance of the housing by giving it the effect of finished article of furniture such as a table or a bench. Fiber strips 31 short of the flange 30 and forms therewith a slotted opening 32 in the front wall of the cabinet when the top wall is closed. opening 32 provides an outlet for the heated air currents which rise from the radiator and are directed therethrough. The openings between the sections comprising the radiator and the front and rear walls 20 and 17 provide free passage for the air as it ascends which is unretarded by the folds on the interior thereof since the folds present slightly projecting and rounded edges to theair currents.

The pan 11 is supported from the folds 25 and 28 by bafile plates 33 and 34 which are mounted upon the pan and spaced away from its top longitudinal edges to form passages for air currents rising from the radiator. Both the front plate 33 and the rear plate 34 are concave towards the pan through an angle of substantially ninety degrees and have a substantially straight hori-- zontal portion projecting over the adjacent edges of the pan with their lower edge portions wedged into the loops 25 and28 respectively. The rear plate 34 is-spaced further from the pan and projects further over the pan than the corresponding portions of the front plate The lower longitudinal edges of the pan are convexed outwardly so that the rising air currents are directed into contact with the concave faces of the plates 33 and 34 which in turn direct the currents over the surface of the m ter-contained in the pan. The pan is spaced above; the radiator slightly to permit passage of air be ncath the pan so as to equalize the flow of currents which are directed against the plates 33 and 34. The air striking the front plate 33 is directed horizontally over the water surface inintimate contact therewith and with the vapor which rises from the water by reason of the proximity of the pan to the radiator. The rear bafile plate is p0- sitioned substantially opposite the opening 32 and directs the air currents from the back of the radiator horizontally over the water surface and on out through the opening. These air currents like those from the front bafiie plate 33 are mixed with the heated vapors and washed of their dust particles. Both sets of currents are also thoroughly saturated, the saturation process being aided by the eddying of the air currents which is caused by the opposing currents meeting at slightly different levels in intimate contact with the water surface and-hcated vapors.

The

In the eddying process the currents from the front haflle plate are merged with the currents from the rear baffle plate and pass out therewith through the openin 32 .in 'a washed and thoroughly saturate condition. 'The battle plates are preferably'positioned rem-- tively close to the top wall so as to prevent any of the air coming from the pan to remain at rest in the housing.

The wedging of the plates 33 and 34 in the folds serves to hold the pan securel in cs1- tion and permits its easy removal or 0 can-- ing and replenishing. The rear plate 34; is pivotally mounted on the pan being provided for that purpose with downwardly extending fingers 35. The lingers are rotatably fastened to the end walls of the pan by rivets or pins 36.andhave a lug 37 which serves as a stop to limit the rotation of the plate 34 towards the surface of the water. The lugs 37 are positioned to stop the plate 34 with its top portion in its normal hor1- zontal position, andto permit rotatlon of the plate outwardly away from the water surface when the pan is removed, thereby facilitating the cleaning and replenishing of the pan- The pan is preferably made substantially as long as the radiator with the batlie plates 33 and 3-1 projecting to partially close oil the open end portions above the valves. Su'liicient space remains between the overhanging ends of the bafiie plates and the housing to permit insertion of the hand to operate the valve. This space 'is normally closed off by horizontal plates 38 which are pivotally' mounted on the baiile plate 34 and are rotatable inwardly to permit access to the valves. The plates 38' prevent the air from rising around the ends of the baille plates and serve to direct the air currents between the halite lates and over the surface .of the water in t e pan.

An alternative mounting for the top wall 16 is shown in Fig. 8 where the rear wall 17 is turned inwardly and outwardly to form an outwardly opening recess in which hinges 39 are mounted. The rear flange of the top wall 16 is-setin slightly so that the angular edge 40st the intersection of the flange with the wall 16 remains inside the vertical plane of the rear wall when'the wall is rotated to open the housing. This arrangement perwas the housing to be positioned with its currents to intermingle in the vapors rising from the humidifier whereby the air is washed of its impurities before it escapes into the room and which further creates in the air a maximum amount of saturation.
